Table of contents
Healthy overnight oats are raw oats mixed with milk and soaked overnight. Hence, the name. Milk softens the oats eliminating the need to cook oatmeal on the stove.
I love making overnight oats while prepping dinner recipes, so easy!
The most common way to make refrigerator oatmeal is in individual glass Mason jars. Add ingredients, stir, place in the fridge and then just “grab and go” for breakfast in the morning. I love to prep pumpkin chia pudding like that, too!
No cooking, no baking and minimal dishes, it’s a win all around just like when I make strawberry smoothie!
Make ahead breakfasts are truly morning time savers! Meal prep healthy waffle recipe or healthy breakfast sandwich for an easy start to the day.
What Are Overnight Oats?
Simple put, cold oatmeal! Raw oats are soaked overnight usually in some type of creamy milk mixture. In the morning, the oats are ready for breakfast or healthy snacks.
You can use any type of oats, although old fashioned oats are more commonly used as they come out super soft and delicious.
This no cook oatmeal is appealing for many as it can be made with gluten free oats, can be dairy free, is perfect for busy mornings when you rely on grab and go breakfast items and can be ate cold or warm!
Health Benefits
- Whole grain: Oatmeal is a whole grain and a nutritious way to start the day!
- Fiber: 1 serving of this healthy overnight oatmeal contains 9g of fiber.ย
- Gut health: Raw oats are a resistant starch and help keep your ratio of ‘good’ to ‘bad’ gut bacteria balanced. You may also like to learn how to make kombucha tea.
- Nutritional value: Because there is no heat involved, you get the full nutritional value that oats overnight have to offer!ย ย
- Less stress: Yes! Meal prep these overnight nights and make mornings a little less hectic.ย
Base Recipe Ingredients
To make basic healthy overnight oats recipe you will need 6 simple ingredients:
- Oats: Technically, any oats will work. The only difference is nutrition and texture.
- Quick oats: Results in a soft oatmeal, creamy consistency. I love baking sugar free oatmeal cookies with them.
- Old fashioned rolled oats: Commonly used in overnight oats as become thick and creamy with a bit of chewiness. I also use these in healthy oatmeal cookies.
- Steel cut (Irish) oats: Final texture will be crunchy and chewy groats that are more runny. These make the best Instant Pot steel cut oats.
- Quick cooking steel cut oats: Theseย offer almost the same nutritional benefits as steel cut oats, with a softer texture closer to rolled oats. They result in overnight oatmeal that is soft with a bit of a bite. These are also good for quinoa breakfast bake.
- Chia seeds: Add fiber, protein and healthy fats, and also make healthy overnight oats thicker.
- Any milk: Any plant based milk like almond milk or soy, coconut or cashew milk, oat milk or regular dairy milk works!
Milk makes your refrigerator oatmeal creamy! You can use water, but your oats will be lacking in both the flavor and texture milk adds.
- Yogurt: You can use any yogurt, Instant Pot yogurt, or even plant-based. It makes oatmeal creamy and adds protein!
- Maple syrup: Adds taste, I wouldnโt recommend using honey because it doesnโt dissolve well in cold milk. For sugar free or low sugar omit maple syrup and use mashed banana instead. Or use calorie free dry or liquid sweetener of choice.
- Vanilla extract: Just a 1/2 tsp of pure vanilla extract, not the artificial kind for best taste. You could also use almond extract for a variation!
How to Make Healthy Overnight Oats
The best part about healthy overnight oats is how quickly you can prep them! Only easier might be green smoothie.
- Prep: Add milk, yogurt, maple syrup, vanilla, oats and chia seeds to any glass container with a lid. Stir well with a spoon.
- Refrigerate: Overnight is the best way to avoid dry oatmeal and give time for milk to absorb into oats. However, healthy overnight oats can be enjoyed after 4 hours.
- Enjoy: In the morning, stir and if overnight cold oatmeal is too thick, adjust with milk. Heat in microwave or enjoy cold.
Variation Ideas
My favorite way is to flavor oats when prepping and just grab and go in the morning.
However, you can always make just the basic healthy overnight oats and top with your favorite toppings like nuts, fresh fruit, healthy granola or leftover healthy fruit salad before enjoying.
My favorite 6 flavor variations to basic healthy overnight oats include:
- Blueberry: Add a squeeze of lemon and 1/2 cup fresh or frozen blueberries. You could swap the berries for strawberry overnight oats. Now you have fruit pie overnight oats, yum!
- Tropical: Use only 1/4 cup any milk, add 1/2 cup canned coconut milk, 1/4 cup chopped pineapple and 1 tbsp of coconut flakes. It’s tropical cheesecake overnight oats!
- Peanut butter overnight oats and jam: Add 1- 2 tbsp of favorite jam and 2 tbsp peanut butter (or any nut butter). You might also like to add a small amount of protein powder like I do in protein cookies.
- Pumpkin: Add 1/4 cup pumpkin puree and 1/2 tsp homemade pumpkin pie spice substitute (or store bought) .
- Banana: Add 1/2 mashed up banana and 1/2 tsp cinnamon.
- Chocolate: Add 1 extra tbsp of maple syrup, 1 tbsp cacao powder and 1 tbsp mini chocolate chips.
The best part of easy overnight oatmeal recipes are the sky is the limit when it comes to variations! I have even used leftover healthy cranberry sauce in them for a seasonal breakfast.
Best Jars to Use
When it comes to best jars to make your healthy overnight oatmeal, you will want to pick a container that is large enough to stir your mixture together without making a mess.
I like to make oatmeal in these 16 oz Mason jars because they fit it in comfortably and with additions. Plastic lids can be used if enjoying oats at home, for on-the-go you must use tight crew-on metal lids.
How to Store and Meal Prep
Store: Refrigerate for up to 5 days. Always check oats before eating. Five days is great for your basic refrigerator oatmeal recipe. If you are adding fruit, you may need to use within 3 days.
Freeze: I have not tried this but I am sure you can freeze leftovers, texture may change upon thawing.
Meal prep: Make a few variations and store in the refrigerator for easy breakfasts all week! You can also double, triple or quadruple the recipe in a large bowl with a lid or plastic wrap. Then portion out in the morning.
FAQs
Per my recipe testing, 5 days is the max, so make these Sunday night to enjoy all work week long!
Really this depends on your healthy eating goals. Overnight oatmeal is full of healthy nutrients and fiber, so it fills you up with wholesome ingredients!
One cup is the serving size, but of course this really depends on your own nutritional goals.
You don’t have to, but it does add the best creamy texture.
Yes, so take that into consideration and don’t fill your jar to the brim. Oats will absorb milk and typically expand 10-15% but this could vary based on type of oats used.
Oats Too Thick or Too Thin?
If your healthy overnight oats mixture is too thick, add more milk.
If your mixture seems too thin, add more oats and let sit for at least 30 minutes.
Can You Eat Them Hot?
I know many cannot eat a cold breakfast. Or let’s say it’s January. Sure thing, warm up the oatmeal in a microwave for 45-60 seconds or on a stovetop in small pot. Treat it like healthy breakfast casserole.
How Long Should I Soak The Oats?
Overnight ๐ Really, though, it will depend on the oats you use. Rolled oats may be good to go within 4 hours. Other oats, like steel cut oats, are best up to 12-24 hours later. Try out a few different oat varieties to discover which refrigerator oatmeal you like the best.

Great to see. Not new though. I grew up on this 50 yrs ago in UK where it is called Swiss Museli. We used to just make a big bowl full of milk soaked, large oats then in the morning add any chopped nuts, fresh or dried fruit. Of course, chia wasn’t in my area back then and the thought of milking an almond…!
Thank you for this wonderful recipe. What size mason jar would you recommend using for this recipe?
Just whatever size you have. You know the most common one, kind of medium small. It doesn’t expand much. Sorry I don’t do much canning, so am not very jar proficient.
This looks delicious and I’m so excited to try it for tomorrow. Should I only make one jar per day or can I make five jars ahead of time since they keep for five days?
Thanks for the great recipe!
Lili
Hi Lili.You can make up to 5 jars at a time.:)
Hubby and I have had them for the past two days. Delicious! Thanks again for a great recipe!
This will probably sound odd but do you cook the oats first or no? Sounds great and would love to try. I have a son and a hubby who hate to cook! They could just grab it and take it to work or eat it at home!
No need to cook the oats. They “cook” overnight in the fridge. Quick oats are instant and pre-cooked basically. Rolled oats are chewier but still no need to cook.
Perfect! I will be stopping at the store tonight to try! Thanks
I keep seeing overnight oats on pinterest and I’m going to break down and try them. Anyone used chocolate almond milk before? That’s all I have. I think in the morning some pecans and fresh blueberries will pair well with it!
Absolutely! Actually your flavour combination sounds great! I will be restocking myself tomorrow for the week too. Haven’t made these in a while but now that my oven is broken I’m going back.
Hi
Just ate it and it was yummy, wish I had made more! Second recipe I’ve made of yours so definitely going to try a third!! Thanks!
That is so great to hear, Connie. Me testing and re-testing recipes works. Enjoy.:)
Where do find chia seeds? And for the quinoa do u put it in as is or cook first?
Chia seeds are sold in majority of grocery stores like Costco, Trader Joe’s, Whole Foods. I probably wouldn’t expect to find them at Walmart.:) I buy this 2lb bag in Costco or you can order on Amazon.
I’m a bit confused about what quinoa. This is overnight oats recipe. You put them in uncooked. If you want to add a little bit of quinoa, you could. Just a tbsp, not more. It has very nutty taste and tastes a bit bitter in the overnight oats. I tried and didn’t like it much.
Quinoa has a bitter/soapy taste if not washed before using. I assume this is true when used raw as well. Try rinsing thoroughly in cold water, really swish them around well with your hand, then drain and use. This will eliminate most of the bitterness.
What if my steel cut oats are not quick? Will it still work? Longer soak?
Yes. The recipe will still work. The oatmeal will be more chewy.
Will taste in the morning! Thank you.
Oh, and by the way, for those who are gluten intolerant, be sure to use Bob’s Red Mill “Gluten Free” version of their steel cut oats.
I’ve seen a lot of recipes for overnight oats, but this sounds like the best one. Can’t wait to make it. I just happen to have some gluten-free steel cut oats, too!
